Exploring the role of genetic diversity and relatedness in tree seedling growth and mortality: a multi‐species study in a Bornean rain forest

Chris Kettle, Claire Tito De Morais, C.D. Philipson, C.R. Maycock, D.F.R.P Burslem, E. Khoo & J. Ghazoul
Where conspecific seedlings occur at high densities, density dependent processes tend to depress their performance and survival relative to co‐occurring heterospecifics. We extend this observation to within‐species genetic diversity and relatedness. We posit that seedling growth and survival increase where there is higher genetic diversity, and lower relatedness, among seedling populations, under the expectation that increased genetic dissimilarity among conspecific seedlings affords greater resistance to pathogens. We used estimates of individual seedling genetic diversity (multilocus...

Data from: Quaternary land bridges have not been universal conduits of gene flow

Emilie Cros, Balaji Chattopadhyay, Kritika M. Garg, Nathaniel Ng, Suzanne Tomassi, Suzan Benedick, David P. Edwards & Frank E. Rheindt
Quaternary climate oscillations are a well-known driver of animal diversification, but their effects are most well studied in areas where glaciations lead to habitat fragmentation. In large areas of the planet, however, glaciations have had the opposite effect, but here their impacts are much less well understood. This is especially true in Southeast Asia, where cyclical changes in land distribution have generated enormous land expansions during glacial periods. In this study, we selected a panel...

Vegetation and habitat data for fragmented and continuous forest sites in Sabah, Malaysian Borneo, 2017

E.H. Waddell, S. Fleiss, B. Bala Ola, A. Bin Sailim, A. Jelling, K.L. Yeong, J. Tangah, S. Benedick, H. King, M. Hughes, C.J. McClean, D.S. Chapman, J.K. Hill & L.F. Banin
This dataset contains records for vegetation in 49 plots across 14 fragmented forest sites and 4 continuous forest sites in Sabah, Malaysian Borneo. Living vegetation and deadwood were surveyed in two or three 0.28-ha plots in each of the 18 sites. In addition to vegetation data, the dataset contains topsoil parameters, measurements of forest structure, and metrics of the degree of forest fragmentation in the landscape surrounding the plots. These data were collected in order...

Data from: Limited contributions of plant pathogens to density-dependent seedling mortality of mast fruiting Bornean trees

Patrick Cannon, Michael O'Brien, Kalsum Yasah, David Edwards & Robert Freckleton
Fungal pathogens are implicated in driving tropical plant diversity by facilitating strong, negative density-dependent mortality of conspecific seedlings (C-NDD). Assessment of the role of fungal pathogens in mediating coexistence derives from relatively few tree species and predominantly the Neotropics, limiting our understanding of their role in maintaining hyper-diversity in many tropical forests. A key question is whether fungal pathogen-mediated C-NDD seedling mortality is ubiquitous across diverse plant communities. Using a manipulative shadehouse experiment, we tested...

Glucocorticoids link forest type to local abundance in tropical birds

Simone Messina, David Edwards, Valeria Marasco, Virginie Canoine, Cindy Cosset, Suzanne Tomassi, Suzan Benedick, Marcel Eens & David Costantini
Selective logging is a major driver of environmental changes in the tropics. Recently, there has been increasing interest in understanding which traits make bird species resilient or vulnerable to such changes. Physiological stress mediated by the steroid hormone corticosterone (CORT) might underlie changes in local abundance of species because it regulates a range of body functions and behaviours to maintain homeostasis in changing environments. We conducted a three-year study to assess: (i) the variation in...

Brevity is not a universal in animal communication: evidence for compression depends on the unit of analysis in small ape vocalizations

Dena Clink, Abdul Hamid Ahmad & Holger Klinck
Evidence for compression, or minimization of code length, has been found across biological systems from genomes to human language and music. Two linguistic laws—Menzerath’s law (which states that longer sequences consist of shorter constituents) and Zipf’s law of abbreviation (a negative relationship between signal length and frequency of use) are predictions of compression. It has been proposed that compression is a universal in animal communication, but there have been mixed results, particularly in reference to...
